The main cause of a "No Signal" notification on your display is an indication that your monitor isn't communicating with your video source device. The device can be a laptop, gaming console, Nintendo Switch, or smartphone. I have a UPERFECT Y Touch-15.6 monitor. I am having trouble switching from using the monitor with USB-C to using HDMI input. The monitor is power by the provided external power supply plugged into the PD port. I have the provided HDMI cable plugged in to my laptop and the monitor. When I power on the monitor it displays no signal for almost 10 seconds then powers off. It doesn’t auto detect the laptop. I can plug into my laptop with USB-C and that detects the video ok. While the monitor is on and displaying, I can press the silver power button on the monitor and change to HDMI. Once I change to HDMI, I can switch to HDMI and it works. The problem is it doesn’t auto-detect HDMI and I cannot manually change the input to HDMI. The input selection does not show up unless I hook up my laptop with USB-C first. As mentioned before, the auto-detect works when using USB-C. Can you help me with this auto-detect issue please? Thank you.

Dual displays can also benefit those who need to keep tabs on constantly changing data while working on a different project on another screen.
